Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Verfahren zum Herstellen eines teilfolierten Bauteils, ein Werkzeug zum Herstellen eines teilfolierten Bauteils und ein solches Bauteil.The The invention relates to a method for producing a partially foliated Bauteil, a tool for producing a teilfolierten component and such a component.
Hintergrund der ErfindungBackground of the invention
In Kraftfahrzeugen eingesetzte Komponenten bzw. Bauteile werden vermehrt aus Kunststoff und nicht mehr, wie zuvor, aus Stahlblech oder Aluminium gefertigt. So werden immer häufiger Kotflügel, Türen, Motorhauben, Dächer und Heckklappen aus Kunststoff hergestellt, wobei diese Kunststoffbauteile vorgegebene mechanische Anforderungen erfüllen müssen.In Vehicles used components or components are increased made of plastic and not, as before, made of sheet steel or aluminum manufactured. So are becoming more common Fender, doors, Hoods, roofs and tailgates made of plastic, these plastic components must meet specified mechanical requirements.
Die Oberflächen dieser Bauteile müssen von den Kunden erwartete Eigenschaften hinsichtlich der äußeren Erscheinungsform und auch hinsichtlich der Schlag- und Witterungsbeständigkeit haben, die bspw. mit aufwendigen Lackierverfahren erfüllt werden. Um diese zeit- und kostenaufwendigen Verfahren zu vermeiden, werden Folien eingesetzt, die nach Hinterformen die Oberfläche des gefertigten Bauteils bilden. In der Regel werden diese Folien zunächst in einem Thermowerkzeug geformt und anschließend nach Abkühlen mit Hinterformmaterialien, typischerweise mit duroplastischen oder thermoplastischen Materialien, hinterformt.The surfaces of these components must expected appearance characteristics of the customers and also in terms of impact and weather resistance have, for example, be met with elaborate painting. To avoid these time-consuming and costly procedures, be Foils inserted, which after Hinterformen the surface of the form finished component. In general, these slides are first in one Thermo tool formed and then after cooling with Backing materials, typically with thermoset or thermoplastic materials, behind forms.
Bei der Fertigung teilfolierter Bauteile, d. h. Bauteile, deren Oberfläche nur abschnittsweise bzw. teilweise durch eine Folie gebildet sind, erweist sich diese Vorgehensweise als problematisch, was dazu führt, dass solche Bauteile oftmals durch Zusammenfügen eines folierten und eines nicht folierten Bauteils hergestellt werden, was die Herstellung sehr aufwendig gestaltet. Daher wird derzeit weitgehend auf den Einsatz teilfolierter Bauteile verzichtet.at the production of teilfolierter components, d. H. Components whose surface only partially or partially formed by a film, proves This approach is problematic, which leads to Such components often by joining a foil and a non-foiled component, which is the production very elaborately designed. Therefore, is currently widely used Partially omitted components omitted.
Zusammenfassung der ErfindungSummary of the invention
Das erfindungsgemäße Verfahren zum Herstellen eines teilfolierten Bauteils sieht vor, dass eine Folie in ein Werkzeug eingelegt wird, die Folie zumindest abschnittsweise mit einem Schieber fixiert und anschließend das Bauteil durch Hinterformen gebildet bzw. gefertigt wird.The inventive method for producing a teilfolierten component provides that a film is inserted into a tool, the film at least in sections fixed with a slider and then the component by Hinterformen is formed or manufactured.
Da mit dem erfindungsgemäßen Verfahren nicht nur der Bereich hinter bzw. auf der eingelegten Folie hinterformt wird, sondern auch ein Hinterformen in dem Bereich bzw. den Bereichen neben der Folie erfolgt, wird ein Bauteil gebildet, dessen Oberfläche nur teilweise durch die Folie gebildet ist, wobei die durch das Hinterformen gebildete Formmasse bzw. der Körper des Bauteils einstückig sein kann, da diese in einem Hinterformvorgang bzw. -prozess gebildet wurde.There not with the method according to the invention only the area behind or on the inserted foil hinterformt but also an under-shaping in the area (s) takes place next to the film, a component is formed, the surface only Partially formed by the film, which by the Hinterformen formed molding material or the body of the component in one piece can be, since these formed in a Hinterformvorgang or process has been.
Durch Fixieren bzw. Festklemmen der Folie durch den Schieber ist gewährleistet, dass die Folie während des Hinterformens nicht verrutscht, so dass ein Bauteil mit einer genau definierten Oberfläche gefertigt werden kann.By Fixing or clamping of the film by the slider is ensured that the film during of forming the mold does not slip, so that a component with a precisely defined surface can be made.
In Ausgestaltung wird die Folie in mindestens einem Randbereich mit dem Schieber fixiert, wobei dieser Randbereich üblicherweise den Übergang zwischen foliertem Bereich und nicht foliertem Bereich des Bauteils definiert.In Embodiment, the film in at least one edge area with fixed to the slider, this edge region usually the transition between foiled area and non-foiled area of the component.
Das teilfolierte Bauteil kann durch Hinterspritzen oder Hinterschäumen oder auch durch Hinterfüllen gebildet werden.The teilfolierte component can by injection or foam backing or also by backfilling be formed.
Das erfindungsgemäße Verfahren ermöglicht, zumindest in den bevorzugten Ausführungsformen, ein definiert form- und kraftschlüssiges Abdichtung einer Folie zu einem angrenzenden Bereich bzw. Raum beim Hinterformen. Dadurch ist ein genau definiertes Abgrenzen von folierten und nicht folierten Bereichen eines Bauteils, das einstückig sein kann, möglich. Beim Hinterformen bzw. Hinterfüllen des Bauteils erlaubt das Verfahren ein positionsgenaues und definiertes Unterscheidungsmerkmal zwischen einem folierten und einem nicht folierten Bereich innerhalb eines oder mehrerer Bauteile bzw. Werkzeugkavitäten.The inventive method allows at least in the preferred embodiments, one defined positive and non-positive Sealing a film to an adjacent area or space when Behind forms. This is a well-defined delineation of foiled and non-foiled areas of a component that are integral can, possible. When undercutting or backfilling of the component allows the method a positionally accurate and defined Distinguishing feature between a foiled and a not foiled area within one or more components or tool cavities.
Da nunmehr teilfolierte Bauteile einfach hergestellt werden können, ist ein reduzierter Folienverbrauch möglich, wobei eine klare Abgrenzung und ein definiertes Abdichten von Folienbereichen, d. h. von folierten Bereichen, gegeben ist.There now teilfolierte components can be easily made, is a reduced film consumption possible, with a clear demarcation and a defined sealing of film areas, i. H. of foiled Areas, is given.
Das erfindungsgemäße Werkzeug dient insbesondere zur Durchführung des beschriebenen Verfahrens. Dieses weist zumindest zwei Formplatten zum Formen eines Bauteils und einen Schieber auf, der zum Fixieren einer zwischen die Formplatten eingelegten Folie vorgesehen ist. Dieser Schieber ist relativ zu mindestens einer der Formplatten zu bewegen bzw. bewegbar.The inventive tool is used in particular for implementation of the described method. This has at least two mold plates for Forming of a component and a slider, which is used for fixing a is provided between the mold plates inserted foil. This Slider is to move relative to at least one of the mold plates or movable.
In Ausgestaltung ist der Schieber im wesentlichen senkrecht zu der mindestens einen Formplatte zu bewegen.In Embodiment, the slider is substantially perpendicular to the to move at least one mold plate.
Das erfindungsgemäße Bauteil ist aus einem Kunststoffmaterial gefertigt, wobei die Oberfläche dieses Bauteil als teilfoliertes Bauteil nur zum Teil bzw. abschnittsweise durch eine Folie gebildet ist. Dabei kann das Bauteil abgesehen von der Folie, die einen Teil der Oberfläche darstellt, regelmäßig einstückig ausgebildet sein.The Component according to the invention is made of a plastic material, the surface of this Component as teilholtiertes component only partially or in sections is formed by a foil. In this case, the component apart from the film, which forms part of the surface, regularly formed in one piece be.
Der Körper bzw. die Formmasse des Bauteils, d. h. das Bauteil bis auf die die Oberfläche des Bauteils abschnittsweise bildende Folie, kann durch Hinterspritzen, Hinterschäumen oder Hinterfüllen, typischerweise einstückig, gebildet sein.Of the body or the molding compound of the component, d. H. the component except for the surface the component partially forming film, can by injection molding, foam backing or backfilling, typically one-piece, be formed.
